My philips TV 27PT6441/37's fuse open after switch on. I found that I have to

"Remove Degauss Resistor 3523 (White Rectangle) And Replace Using
Location 3507 With Service Code 2122 663 00019, A 3 Ohm Ptc Resistor. Give Close Attention To The Marking On The Cba For 3507."

But I am new in electronic. The degauss resistor have 3 legs. The first and second legs locate at 3509 position and the third leg locate on 3507. The new ptc resistor have 2 legs. I don't know which position I have to use for new resistor (Thermistor 2122 663 00019).

Thanks,
Sukit T.
